EMDR therapy facilitates the accessing and processing of traumatic memories and other adverse life experiences to bring these to an adaptive resolution. When an individual undergoes EMDR, memories of a traumatic event are accessed in a specific way. It combines eye movements (there are other forms of bilateral stimulation such as left and right tapping) and guided instructions to help the person reprocess what they remember from the negative experience. In the reprocessing phase, the brain can “repair” the mental injury from that memory. The person will be able to remember the event and no longer feel like they are reliving it (e.g., PTSD), hence the related feelings become much more manageable.
EMDR therapy has been extensively researched and practiced with high rates of success. It has been endorsed by the American Psychiatric Association (APA); the US Departments of Veterans Affairs and Defense; The World Health Organization; and the Substance Abuse and Mental Health Services Administration of the Dept. of HHS. EMDR is a psychotherapy treatment that was originally designed to alleviate the distress associated with traumatic memories (i.e., PTSD, depression, anxiety). https://www.emdr.com/what-is-emdr/
